#30 骰子轉轉轉－Dice Game Pig

這次彼得出了一個作業給我，叫做小豬骰子
還滿好玩的！也算是比較簡單一點的遊戲
但還是做了好久才做出來

成品如下：

又完成了一項不可能的任務！
而且開始上進階班之後，覺得同學都好厲害，也越來越緊張
發現自己的能力還差很多，加油！不能放棄

話不多說就來介紹一下這個遊戲吧！
遊戲規則很簡單，每一個玩家輪流骰骰子，看誰的點數先累積到100分就獲勝，程式邏輯也不會很複雜，但高手大大們不會笑我寫的程式吧？

完整程式碼如下：

import UIKit

class ViewController: UIViewController {
    
    //把需要用到的UI元件拉進Outlet
    @IBOutlet weak var player1TotalLabel: UILabel!
    @IBOutlet weak var player2TotalLabel
    : UILabel!
    @IBOutlet weak var player1DicePointLabel
    : UILabel!
    @IBOutlet weak var player2DicePointLabel
    : UILabel!
    
    @IBOutlet weak var player1View: UIView!
    @IBOutlet weak var player2View: UIView!
    
    @IBOutlet weak var diceImage: UIImageView!
    
    @IBOutlet weak var rollButton: UIButton!
    @IBOutlet weak var holdButton: UIButton!
    @IBOutlet weak var resetButton: UIButton!
    
    //宣告玩家的分數、總分
    var player1DicePoint = 0
    var player2DicePoint = 0
    var player1Total = 0
    var player2Total = 0
    let gameScore = 100
    let diceImageView = ["dice1","dice2","dice3","dice4","dice5","dice6"]
    var currentPlayerDicePoint = 0
    
    //宣告目前是哪一個玩家的回合，之後進行判斷會比較清楚
    var isPlayer1Turn = true
    
    //切換玩家
    func togglePlayer() {
        isPlayer1Turn.toggle()
        }
    
    //設定遊戲結束時顯示對話框
    func gameEnd(winner: String) {
        let alertController = UIAlertController(title: "Game Over!", message: "\(winner)獲勝!", preferredStyle: .alert)
        alertController.addAction(UIAlertAction(title: "確定", style: .default, handler: nil))
        present(alertController, animated: true,completion: nil)
    }
    
    //重置遊戲
    func resetGame() {
        player1Total = 0
        player2Total = 0
        currentPlayerDicePoint = 0
        player1TotalLabel.text = "0"

    }
